Title: Differential shrink wrapping - using covers thermoformed for selective recovery of the cooler stage forming
IPC: B29C51/42
Filed: 1972-04-24
Abstract: Thermoplastic capsules etc. which exhibit preferential thermal shrinkage in one direction by being formed partly at a temp. T1 slightly below the matl. m.pt., then partly at a temp. T2 slightly above the softening pt., and then chilled. For mfr. of packaging, bottle closures, etc., made of e.g. polystyrene, polyolefins, PVC, etc., by shrink wrapping at a temp. T3 between T1 and t2. Preferential shrinkage can reduce matl. wt. by avoiding shrinkage in unwanted directions during shrink wrapping which has to be compensated by extra dimensions/material. Heating to T3 only promotes recovery of forming effected at T2, not T1. Bottle neck covers can be preformed in two stages, to a cylindrical shape at T1 and dilated at T2 so that only radial recovery occurs during fitting.

Title: Compressed propellant pellet loading system - for sealing guns using metal charger
IPC: B25C1/08
Filed: 1973-11-14
Abstract: Charger for a sealing gun is intended to hold the agglomerated powder pellets and introduce them into the gun one by one. The pellets are placed in a carrier in the shape of a flattened 'U'. The end of the charger is placed into the gun up to the rounded shoulder of the supporting body and comes up against the shoulder of the firing pin carrier. The body advances until a spring-loaded ball is pressed into a hole in the handle. The last pellet during the movement, leaves the charger and is pushed by the next pellet into the housing through the opening; the handle is drawn back and the operator extracts the charger. The gun or pistol is closed, the sealing bolt introduced and it is ready for use. The withdrawn charger is likewise ready to be refilled. The small inflammable, friable pellets are protected by the charger up to the time of use; all direct handling is avoided.

Title: Cutter for cutting yarns of lace fabric has cylindrical blade - cooperating with end of a cylinder having notches in which yarns locate
IPC: D06C13/04
Filed: 1973-11-16
Abstract: A cutter device includes a cylinder having oblique notches formed in its lower end and a cylindrical blade concentric with the cylinder. The cylinder is located above a lace fabric and is rotated so that yarns connecting viscous patterned areas of the lace are forced into the notches and travel up the oblique walls of the notches onto the cutting edge of the blade whereby they are cut. The yarns connecting the various patterned areas of the lace may be of different lengths and under different tensions. The cutter device can efficiently cut all these yarns and is quicker than manual cutting.

Title: Brake control valve for motor vehicles - is operated by electric difference signal dependent on actual and required force
IPC: B60T8/1761
Filed: 1974-01-14
Abstract: The monitoring device produces an electric signal specified by the actual value of the applied pressure and there is a circuit to generate a signal indicating the difference between the command signal and the monitored signal and the normal value. As the difference increases an increased pressure is applied to the brakes by means of a regulating valve with proportional output. This has a component that moves depending on the applied pressure and a spring connecting this to the main valve. The servo valve operates in dependence on the difference signal. Inside the monitor there is a transducer connected to the moving component of the control valve. There are two working surfaces in the moving component.

Title: Thermoregulator valve for I.C. engine cooling system - contains spacer dislodged during topping-up after egassing
IPC: G05D23/02
Filed: 1974-03-05
Abstract: Thermoregulator valves are used in the cooling water circuit of internal combustion engines to prevent flow of water until the engine has reached a particular temperature. Refilling and degassing times are reduced. A thermoregulator valve comprises a frame (1) containing the seat (2) of a valve (3) which slides on a shaft (4). One end of the shaft engages with a bored hole (5) in the case while the other end is engaged with a thermosensitive element (6) mounted on the valve (3). A spring (7) exerts a pressure between the case and valve to retain a semi-cylindrical spacer (8) between the valve and bored hole (5). This spacer is dislodged by the flow of water during the topping up process after degassing the system.

Title: Fold patterns for tyre carcass reinforcement beside the bead - to reduce risk of progressive sidewall delamination
IPC: B60C9/02
Filed: 1974-07-19
Abstract: Tyre construction incorporates extra reinforcing gaiters alongside the carcass reinforcing plies both being doubled back around the bead reinforcing hoops, the free edges of both the carcass plies and the adjacent gaiters turned back again towards the rim of the tyre. Doubling back of the free edges avoids propagation of delamination radially up the side wall due to oscillation of the edge as the tyre flexes with the rolling progression of the compressed zone in contact with the road.

The acid stabilises the sols., which are stable at high conductivities (e.g. 20,000-40,000 umho/cm at 21 degrees C) and high solids contents (up to 45%). The polycarboxylic acid pref. has 2-4 COOH gps. separated by 3 C atoms; prefd. acids are citric acid, glutaric acid, nitrilo-triacetic acid, EDTA and adipic acid. The acid can be added either (a) to the negatively charged silica sol. while maintaining a pH of 6.5-9 (esp. 7-8.5) or (b) to the Al salt at the same time as the silica sol. The final pH of the mixt. is pref. 4.0-5.5. The basic Al salt is pref. a chloride or nitrate, esp. Al2(OH)5Cl. A mixt. of 175 parts of an alkali-stabilised silica gel ("Ludox" HS 70) and 2.04 parts glutaric acid was homogenised, the pH being adjusted to 8.0 with 1.5N NaOH. The mixt. was added to 44.6 parts of chlorohydrol (soln. of Al2(OH)5Cl contg. 23.5% Al) and made up to a total wt. of 271 parts with H2O. The product had a pH of 5.0 and a viscosity of 19 cP. When heated at 100 degrees C, the sol. remained stable for 33 hr. (corresp. to >=1 year at room temp.); the corresp. value for the unstabilised sol. was 7 hr.
